Troubleshooting
The number format you use may be invalid, or the called number has not answered 
within 10 tries, or you are calling to a wrong phone number.
The phone may be busy: data or fax is being sent or received, the communicator is 
being used as a fax modem. Wait for the data/fax transmission to end, or drop the 
call by pressing the   key on the phone keypad.
Fax/data barrings or fax diverts may be active. You can define the Fax barrings/
diverts in Tools > Account settings… > ECM in Messaging.
Fax reception: Your SIM card may not have a fax number. 
Mail reception: You have not subscribed to a remote mailbox service, or the mail 
service you are using uses another mail protocol than what you have selected. 
(Check with our Internet Service Provider whether you should be using POP3 or 
IMAP4.) If you are using secure connections, your remote mailbox service also has 
to support secure connections. There may also be a transient problem with the 
remote mailbox service, or the Internet servers between the communicator and the 
remote mailbox. Try again after a couple of minutes, and then contact your 
Internet Service Provider.
Mail sending: You have not subscribed to a remote mailbox service, or the mail 
server delivering your mail does not comply with the SMTP protocol. If you are 
using secure connections, your remote mailbox service also has to support secure 
connections. There may also be a transient problem with the remote mailbox 
service, or the Internet servers between the communicator and the remote 
mailbox. Try again after a couple of minutes, and then contact your Internet 
Service Provider.. If you are using the Upon request sending option, mail must be 
sent in the Document outbox, see ‘Outbox’ on page 161.
